Update on my issue...Well, I checked voltage on all the wires in the FPDM and they checked out So it seems my problem was to have been a bad fuel pump....
Ordered a Carter P76018M from RockAuto (only $104 - got to love RA prices) and put it in the over the last couple of nights. Being that I spent 70K+ miles in ChicagoLand the d*mn nutzNboltz under my car are mostly rust so dropping the fuel tank turned out to be a big PITA lol Anyway - a couple of days running (this pump is much quieter then the OEM) and so far the fuel pump seems to be doing well and taking care of my SVT, let's hope it stays that way :)
If anyone searches this later - hope it helps!

|NJSVTGUY||I would disconnect the fuel line to the fuel rail. Put it in an empty water bottle and have someone turn the key. See if you get fuel, I suspect not.|

So - Pulled the Crank Sensor and it was dirty but fine (no rub marks). Sprayed some carb cleaner in the intake and the car started for a second, guess that kind of rules out spark issues....
No CEL but Hooked up the scanner got this code: P1237 - Fuel Pump Secondary Circuit Malfunction http://engine-codes.com/p1237_ford.html
Fuel Pump Driver Modules (FPDM) controls the voltage to the Fuel Pump in order to maintain proper fuel pressure over the full operating range of the engine. The DTC indicates the FPDM detected a fuel pump secondary circuit fault. The FPDM sends a message to the PCM through the FPM circuit, indicating this failure was detected. The PCM sets the DTC when the message is received.
- Open or shorted FP PWR circuit
- Open FP RTN circuit to FPDM
- Open or shorted circuit in the fuel pump
- Locked fuel pump rotor
- Damaged FPDM
Um - all that means what now ????

The crank sensor is on the block just above the oil pan below Cyl 4 , its the only think on the block in that area with wiring going to it

The crank sensor is on the transmission housing under the intake snorkel tube. You can pull the sensor out and check for impact marks.
DTCs stands for Diagnostic Trouble Codes. You can get a simple code reader and check Key on Engine Off DTCs.

"car wont start because of the fly why rubbing on the back of the crank sensor"
Is there a way to check for this?
Where is this sensor?
Thanks for your reply (even though my post is now gone?)!
? DTCs ???

The Focus is known to ware off the back side of the crank sensor , if it does this you get no fire and car wont start , most guys turn the car off , go in , come back out and car wont start because of the fly why rubbing on the back of the crank sensor
This is why I listed the crank sensor

There is a fuel shut off inertia switch on the passenger side kick panel. If someone kicks this it shuts the fuel pump off. It has a reset button on the top of it.
If there was no crank sensor input then there would be a CEL light on for random misfire on startup. Have you checked DTCs?
Coil pack is not connected or damaged. You can test for spark using a grounded spark plug tester.
Other than those basics you'll need to start checking engine DTCs for some clues to what is going on. My next guess would be something is wrong with the throttle position sensor or wiring.
